【中文标题】由于目标被视为被动，无法在被动事件侦听器中阻止默认值？为啥滚动时出现此错误？【英文标题】：Unable to preventDefault inside passive event listener due to target being treated as passive? Why this error upon scrolling?由于目标被视为被动，无法在被动事件侦听器中阻止默认值？为什么滚动时出现此错误？ 【发布时间】：2019-08-28 02:48:59 【问题描述】：我正在使用 chrome 最新版本。我的应用程序抛出错误：
Unable to preventDefault inside passive event listener due to target being treated as passive. See https://www.chromestatus.com/features/6662647093133312
它阻碍了它正确滚动的能力，即生涩的滚动。我在互联网上尝试了很多解决方案，但无法解决。
请帮助我。我正在使用 css3、引导程序和 html。我尝试添加被动属性等，但似乎没有任何效果。
我的代码：

【问题讨论】：
What are passive event listeners?的可能重复 使用被动侦听器意味着您承诺不致电preventDefault。如果您希望能够做到这一点，请不要使用被动侦听器。
@CertainPerformance：我该如何阻止它？
我看过帖子但不知道在哪里使用该代码
Chrome 已将被动事件侦听器设置为默认值（忽略标准），因此无法再绕过它，CertainPerformance。
【参考方案1】：
我知道它有点旧了。但我找到了解决我可能遇到的问题的方法。
问题是；车轮事件需要是被动的还是非被动的。现代浏览器（例如 chrome）因为它的被动=真而受到威胁。所以异常上升了。
查找添加轮事件侦听器，例如“window.addEventListener('wheel', func)”或“window.addEventListener('wheel', func, true|false)”并将其更改为“window.addEventListener('wheel', func, passive:false)”。
我的问题就这样解决了。
【讨论】：
这个答案很棒！如果有这样的文档参考就完美了：developer.mozilla.org/en-US/docs/Web/API/EventTarget/…【参考方案2】：如果您的代码像使用我在 wordpress 中安装的名为 advanced-scrollbar/js/jquery.nicescroll.min.js 的插件一样被缩小，那么您应该像上面提到的 FerhatOzkanun 一样在源代码中查找细节并相应地更新它，清除缓存并重新运行，然后再次检查。对我来说，这个解决方案有效..
你可以先找这样的东西：
/*comment this ->return*/b.preventDefault(); /*add this*/passive:false
并查找此实例并替换它。
/*comment this ->e||!1*/ /*add this*/passive:false
指的是前面提到的window.addEventListener('wheel', func, true|false)。
【讨论】：
以上是关于由于目标被视为被动，无法在被动事件侦听器中阻止默认值？为啥滚动时出现此错误？的主要内容，如果未能解决你的问题，请参考以下文章
无法在被动事件侦听器 jQuery Mobile 中阻止默认值
react-datepicker“无法阻止被动事件侦听器调用中的默认值”
[Violation] 向 Angular 4 项目中的滚动阻止“touchstart”事件添加非被动事件侦听器是啥意思？
